CONTROL-LEVER LOCK FOR MOTOBFVEHICLES.

Specification of Letters Patent.

Patented Apr. 1,1913.

Original application filed February 27, 1908, Seria1 No. 418,056.Divided and this application filed March 15, 1912. Serial No. 683,999.

To all whom it may concern 2 Be it known that I, HIRAM P. MAXIM, acltizen of the United States, and a resident of Hartford, in the county'of Hartford and through this sleeve,

State of Connecticut, have invented an Im provement in Control-LeverLooks for Motor-Vehicles, of which the following is a specification.

My invention relates more especially to that class of motor vehiclesdesigned for use on highways, and an object of my invention, amongothers, is to provide a controlling mechanism for such motor vehicles inwhich mechanism the liability to accidental operation shall beremovedand a further object is to provide a combined steering andcontrolling mechanism that shall be extremely simple and efiicient. p

One-form of device embodying my'invention and in the construction anduse of which the objects above mentioned, as well as others, may beattained is illustrated in the accompanying drawings, in which--- 7Figure 1 is a view in elevation of the steering and controllingmechanisms, with parts cut away to show construction. Fig. 2 is a detailperspective view, scale enlarged, showing the construction and operationof the controlling mechanism.

The mechanism shown, and described herein is particularly applicable tothe motor vehicle forming the subject matter of my co-pendingapplication, filed February 27th, '1908, of Serial Number 418,056, thesub'ect matter of this application being a division of said co-pendingapplication.

In the accompanying drawing the numeral 83 denotes a steering postbracket secured to the under sur ace of a side bar 34 and preferably toeach of the outer and inner flanges 35-36, as shown in-Fig. 1 of thedrawings. This bracket extends in a diagonal direction downward andlaterally of the vehicle frame, having a tubular steering post neck 84at its outer end, slotted as at 85, screws 86 serving to clamp .the neckabout a supporting sleeve 87 This supporting; sleeve is securely held,as described, projecting upward from the neck as shown 1n Fig.

this post having secure at itsyloweriend and under the bracket 83 asteerin larm 89 suitably connected by a rod 90'w1th1'the steeringmechanism appursuch shoulder.

.pawl. Should the 1.- A steerin 6st 88 projects ition g p d g vnwaidbefore the handle can'be moved tenant to the front wheels of thevehicle. A controller sleeve 91 is mounted upon the supporting sleeve87, said controller sleeve bearing a toothed segment 92 meshing with atoothed segment 93 upon a controller shaft 94 extendin to the controller(not shown). The control er for the sake of brevity, has not beenillustrated herein, but its construction and operation will be readilyunderstood by those skilled in the art, and the shaft 94; ma be suitablyconnected with the cont-roller s aft or such shaft may ,be extended tothe position shown. Ithas a suitable-bearing in a controller shaft-neck95 extending from the bracket 83.

My invention contemplates the provision of means to prevent accidentalor unintentional operation of the controller handle, in the mechanismherein shown it being impossible to move the controller handle from itsforward driving position or off position to the reverse position andvice versa.

In the form of mechanism shown herein a cont-roller handle 96 extendsfrom a band 96' mounted to rotate with the controller sleeve 91,beingsuitably held against lengthwise movement thereon. This band is locatedadjacent, in the present instance underneath, to a controller ring 97having slots 9899 adapted to receive a pawl 102 movably mounted "on theband 96'-. As

shown herein, the slots 9899 are out of line with each other,but-are-connected by an opening including shoulders 100 and 101.

From the drawing it will be observed that in a movement of thecontroller handle backward along the slot 98 or toward the shoulder-101, the pawl 102 will encounter At this point the controller move thehandle to reverse the direction of movement of the vehicle the pawl 102must be. moved upward through the connecting opening between the slots9899, this requiring a special operation to move the pawl be located inthe e lever handle toward thepawl will hich 1s the off slot 99, inmoving t the forward driving position,

encounter the shoulder 100 and the pawl 102 must be moved to cause thevehicle to move forward. A binding screw 96 pro'ects into the band 96,and its'inner end bin s against the pawl 102 handle is in its ofiposition. In order to I While I have shown and described herein to adegree suficient to hold the pawl in any position, but at the same timeallow a movement for the purpose intended. Any suitable means ofengagement between the screw and \pawl may be employed. The controllerhandle, for the purpose of clearness in illustration, isilocated indifierent positions Figs. 1' and 2, and a steering handle 103 is securedto the upper part of the steering post 88.

a satisfactory formof mechanism embodying theinvention it is to beunderstood that the invention may be embodied in constructions diiierentfrom that herein shown and described.
